Many of us are attuned to our own problems usually and rarely stop to consider what other people may have to go through on a daily bases. That leads some people to feel more empathy/sympathy for some while showing a careless mentality towards others.
Some will feel sorrow for the innocent slain cops, while making every excuse in the book for the deaths of Tamir Rice and Eric Garner. Some people’s heart will go out to the ranchers in the West Cost losing their land due to government manipulation, but not feel anything about some Native American people’s land being pushed over by corporate interest or the unconstitutional activities against the people of Ferguson.
I try not to be that type of a person; I feel pain/sadness for Wenjian Liu, Rafael Ramos, Tamir Rice, Eric Garner, Shawn Bell, and anyone else killed or any person who is being taken advantage of by any entity.
The reason why our country is so screwed up (always have been actually) is due to the simple fact/reality that no one stops to consider. Consider why racism, sexism, homophobia, etc are still an issue in our society centuries later. Why one death is more important and heart-wrenching than the other?
Our personal bias, ideology, media outlet we trust and perspective always come into play and it is a type of group or mob mentality. Some people never move passed that, which is why as much progress we have claimed to have made; in reality we really are stagnate. One of the reasons that politics is an extremely easy profession when you think about it. It is really easy to get people to hate each other, really easy. It is simple to play on race in divisive ways (Race itself was partially created for that reason). Many of the isms were created to draw up fear, suspicion, and hatred for others to justify atrocities that would soon take place; still do.
Unless people can grow up and confront these issues head on, it will never change. Some of the seemingly progress we have made, was due to the fact many were brave enough to do this.
I also want to add that we can be a revengeful species; I notice the people who share the brunt of revenge be it on an individual bases or an entire country, innocent people usually suffer the most.
Columbine for example; some kids did horrific things to Eric Harris and Dylan Klebold, but their reaction was to take innocent lives. 9/11; what those terrorist did was disgusting, but our reaction lead to a lot more innocent deaths. This type of mentality leaves a society (not just ours of course) in a constant state of senseless violence.
Lastly; I want to give my sincere condolences to the families who have fallen victim to police brutality and to the families who have lost such dignified officers, who put their life on the line for others.
